[rules-users] Optaplanner ShiftAssignment Employee is null

[ns]

Hi,

I have a strange error. When I get my final roster, I do:

System.out.println(final_roster.getShiftAssignmentList());

I get a list of all the employees (with their names) assigned to a certain
shift on a certain date.

Now I would like to iterate over this list to save it to my database, so I
do the following to test:

for (ShiftAssignment shiftAssignment : roster.getShiftAssignmentList())
{
     System.out.println("Shift assignment: " + shiftAssignment.getEmployee()
+ " - " + shiftAssignment.getShiftDate() + " - " +
shiftAssignment.getShift().getLabel());
}

But now the shiftAssignment.getEmployee() returns null. How can this happen?
Thanks
